  20. 5. Conclusion

  21. Conclusions • Nuclear reaction data base: Basic infrastructure in physics and engineering We do not set special purpose on the database. • International network of data compilation is working very well. • General purpose file → Derived files (energy, astro,...)→ Users • We did a trial to develop a derived experimental data file (NRDF/A) for astronuclear reaction data evaluation. • Completeness of astronuclear data in the primary database (NRDF/EXFOR) must be checked. • Thanks for all experimentalists who provide us numerical data!! • Citation and acknowledgementto our databases are appreciated. (Resource of budget and man power is poor.) http://www.jcprg.org/
